Bitumen

The hull is optimized for an improved propulsion efficiency. The vessel is divided into 12 cargo tanks. The design cargo density is 1.025 ton/m3, the cargo density can be up to 1.05 ton/m3 at 15°C and temperatures up to 185°C.

The propulsion system consists of a four-stroke engine with a single screw controllable pitch propeller. The electric generating system consist of two main diesel generators and one shaft generator. The main fuel is HFO and MGO, the design is prepared for a change to methanol. The vessel has a very low fuel consumption of 10.8 t/24h at a speed of 12.5 knots at 75% MCR with 15% sea margin and an output of 300 kW from the shaft generator at design draught. The installed power is 4060 kW.

The vessel will be equipped with diesel electric propulsion, twin screw 2×360° revolving azimuth thrusters, having Integral cargo tanks and with FKAB F-Bow design, for asphalt transportation services.
It is designed for transportation of Asphalt at 180°C with integral tanks.

The FKAB design is a bitumen, chemical and product oil tanker, tier III, twin skeg with independent cargo tanks for bitumen and asphalt with a temperature of up to 200°C. The vessel is designed with single bottom and double sides for ballast water. The high temperature variations require special design considerations, mainly because of thermal expansion of tanks and pipes. The cargo tanks consist of two blocks, forward and aft of the cargo room, with six tanks respectively in each block.The cargo tank support are arranged in such a way that it allows free expansion in all direction. There is no structure inside the cargo tanks.

Twin skeg powered by two (2) medium speed four stroke dual fuel (diesel / LNG) engines coupled to controllable pitch propeller and two shaft generators connected via gear boxes, shaft generators will also be used as motors (PTI) when running on slow speed with just one main engine. Shaft generators will be connected to the electric net via a DC-link and frequency converters allowing variabble speed of the engine /propeller for both PTI and PTO. In order to save fuel the shaft generator is connected via a frequency converter allowing optimum propeller rpm at various speed.

The vessel is designed for a service speed of 11,0 knots at 80% MCR with 15% sea margin, with clean hull, at a draught and even keel with an output from the shaft generator of 250 kW. Fuel consumption of main engine in LNG mode at 11.0 knots at design draught excluding shaft generator and excluding sea margin under ISO standard ambient conditions and LCV 48,000 kJ/kg to be about: 9,3 ton per day Fuel consumption of main engine in MGO mode at 11,0 knots at design draught excluding shaft generator and excluding sea margin under ISO standard ambient conditions and LCV 42,700 kJ/kg to be about: 10.3 ton per day

The FKAB I15 design is a bitumen, chemical and product oil tanker with independent cargo tanks for bitumen and asphalt with a temperature of up to 200°C. The vessel is designed with single bottom and double sides for ballast water. The high temperature variations require special design considerations, mainly because of
thermal expansion of tanks and pipes. The cargo tanks consist of two blocks, forward and aft of the pump-room, with four and six tanks respectively in each block.The cargo tank support are arranged in such a way that it allows free expansion in all direction. There is no structure inside the cargo tanks.

Propulsion is provided by a four (4) stroke, medium speed diesel engine with a gearbox fitted with and shaft generator for PTO and PTH coupled to a CP-propeller. Power for take me home, PTH, from auxiliary engines. In order to save fuel the shaft generator is connected via a frequency converter allowing
optimum propeller rpm at various speed. The vessel is designed for a service speed of 13,0 knots at 75% MCR with 15% sea margin, with clean hull, at a draught and even keel with an output from the shaft generator of 250 kW.

Fuel consumption of main engine in LNG mode at 13.0 knots at design draught excluding shaft generator and excluding sea margin under ISO standard ambient conditions and LCV 48,000 kJ/kg to be about: 11.9 ton per day Fuel consumption of main engine in MGO mode at 13.0 knots at design draught excluding shaft
generator and excluding sea margin under ISO standard ambient conditions and LCV 42,700 kJ/kg to be about: 13.8 ton per day.
Effective LNG tank volume to cover a cruising range of 11700 nm.

The FKAB I14 design is a bitumen, chemical and product oil tanker with independent cargo tanks for bitumen and asphalt with a temperature of up to 250°C. The vessel is designed with single bottom and double sides for ballast water.
The high temperature variations requires special design considerations; mainly because of thermal expansion of tanks and pipes. The cargo tanks consist of two blocks, forward and aft of the pump-room, with five and four tanks respectively in each block. Each tank block is only fixed in the middle and therefore able to move longitudinally, depending on the temperature.

There is no structure inside the cargo tanks.
Propulsion is provided by a medium speed diesel engine with a gear and shaft generator coupled to a CP-propeller. Take me home device through PTI from the auxiliaries.
In order to save fuel the shaft generator id connected via a frequency converter allowing optimum propeller rpm at various speed.
